Hi R,
Again struck with regular expressions...
Suppose,
S=c("World_is_beautiful", "one_two_three_four","My_book")
I need to extract the last but one element of the strings. So, my output should
look like:
Ans=c("is","three","My")
gsub() can do this...but wondering how do I give the regular expression....
